I need some help...I bought an R4 about 2 months ago and I love it. However, I think it may be broken. I recently upgraded my firmware to 1.13, haven't got around to getting 1.14, and I'm having some problems. My R4 no longer boots games, hardware, or multimedia. When I checked on my computer, I noticed a bunch of corrupted files. Their names were...odd....and some files were over 5GB, despite me having only a 1GB micro SD card. This also makes me wonder if it's the SD card. It's a Lexar 1GB, assembled in Taiwan. I tried reverting to older firmware, formatting, and I still cant get it to work. Also, maby I formatted it wrong for the R4? What should the File System and the Allocation Unit Size be? Maby that could do it? Sorry, but I really don't know much about the R4. Any help would be appreciated. After scanning some of the other topics on the board, I wonder if the USB reader is to blame? So many things could be wrong with it, but I have no idea which is really the problem... I think it may be the SD card. I've tried reformatting it again, and it took a LONG time to write just the firmware; over 5 minutes.
